The first conqueror established himself in a strong castle at Newport, which formed the _Caput Baroniæ_, or chief place of the district. Here the Lord Marcher of Kemaes held his court in almost regal state, exercising practically unlimited control over the lives and property of his newly-conquered vassals. After the manner of the times, the Lord of Kemaes was empowered to deal summarily with felons, for whom a gaol was provided within the castle precincts, where a gibbet stood on a mound called by the natives Cnwc y Crogwydd, or Gallows Tump. Amongst the privileges peculiar to this lordship was the patronage of the British Bards, and the disposal of a much-prized silver harp, which was treasured in the ancient abbey of St. Dogmaels, near Cardigan. Standing upon a gentle declivity overlooking the town and bay, Newport Castle owes its origin to William, son of Martin de Turribus, the conqueror of Kemaes. The date of its erection appears to have been about the close of the eleventh century, but the castle was probably altered or enlarged by subsequent rulers. In Queen Elizabeth's time that curious antiquary George Owen paid a visit to Newport Castle, in which he noticed 'faire and lardg Roomes'; moreover, he tells us the place 'was moatid with a clear Springe of swete running Water, out of whiche, after it had pleasured the Eye in that capacitie, by a sluice it was let foorth to drive the myll, called the Castle myll, adjoininge the sayd moate.' Of this lordly structure the entrance archway, flanked by two noble crenellated towers, are the best preserved features; but extensive ruins of walls and circular bastions, encompassed by the half-obliterated moat, may still be traced upon its western side. Nestling beneath the castle, on the outskirts of the town, stands the handsome parish church of St. Byrnach. The original edifice is said to have been erected by the builder of Newport Castle, but the present Decorated structure has superseded a building of later date that was the very epitome of ugliness. Within the church stands a very early font, probably the original one of Norman times. Of the finely wrought and gilded rood-screen it is said once to have possessed, not a vestige has been preserved. St. Byrnach, the patron saint of Newport Church, was an Irishman by birth, and a contemporary of St. David. He appears to have been held in high esteem throughout all this district, where many of the parish churches are dedicated to his name. This holy man is supposed to have led the life of a hermit, dividing his time between Buarth Byrnach, or Byrnach's Fold, on the singular mountain called Carnedd Meibion Owen, and the rocky recesses of Carn Englyn, the Angel's Peak, above Newport town, a hill that derives its name from a tradition that St. Byrnach was nourished by angels during his lonely sojourn there.
